Liquid oxygen, liquid nitrogen and liquid argon are widely used in liquid gasification stations to supply gas directly or fill bottles. In order to ensure the safe operation of the aerator, safety control points should be set up and the following matters should be paid attention:
1) set the low temperature control interlock point of the low temperature liquid outlet air purifier. Control the gas outlet temperature to 5 ~ 30℃. When the outlet temperature is lower than 0℃, the liquid pump will be cut off automatically and the liquid will be stopped from entering the air purifier. The air purifier without liquid pump will give out sound and light alarm;
2) set air purifier water temperature control interlock point. Control the water temperature at 40 ~ 60℃. When the water temperature is lower than 30℃, the liquid pump will be cut off automatically, and the liquid will stop entering the air purifier;
3) set the pressure control interlocking point of gasification gas outlet, and control ...
